Create a fileset

1. Log on to the NAS console.

   Parameter	Description
   Fileset Path	Specify the absolute path of the fileset in the file system. The fileset path must meet the following requirements: The path must start and end with a forward slash (/). The path must be a new path and cannot be an existing path. If the fileset path is a multilayer directory, the parent directory must be an existing directory. You cannot rename a fileset path. The path cannot be a symbolic link. The maximum depth of a path is 8 layers. The total length of the path cannot exceed 990 characters. The name of a single-layer directory can be a maximum of 255 characters in length and can contain uppercase and lowercase letters, digits, underscores (_), periods (.), and hyphens (-).
   Fileset Name	Specify a name for the fileset. The name must meet the following requirements: The name must be 2 to 128 characters in length and can contain English and Chinese characters. The name must start with an uppercase or lowercase letter or a Chinese character. The name cannot start with http:// or https://. The name can contain digits, colons (:), underscores (_), and hyphens (-).
   (Optional) Deletion Protection	Set the deletion protection feature for the fileset instance. After you enable deletion protection for a fileset instance, you cannot delete the fileset instance in the console or by calling an API operation. If you want to delete the fileset, you must disable the deletion protection feature.

Delete a fileset

1. On the Fileset tab, find the fileset that you want to delete and click Delete.

2. Review the details of the fileset that you want to delete and click Confirm Deletion.

Edit a fileset

You can modify the name of a fileset and configure the deletion protection feature.

1. On the Fileset tab, find the fileset that you want to edit and click Edit.

2. In the dialog box that appears, modify the fileset name or configure the deletion protection feature.

View fileset capacity monitoring

You can view capacity monitoring data for a fileset only in the Cloud Monitor console or by calling Cloud Monitor API operations.

• Use the Cloud Monitor console

  1. Log on to the Cloud Monitor console.

  2. In the navigation pane on the left, choose Cloud Resource Monitoring > Cloud Service Monitoring.

  3. On the Cloud Service Monitoring page, enter CPFS and click CPFS (Old version).

  4. On the CPFS (Old version) page, select a region, find the file system that you want to manage, and then click Monitoring Charts in the Actions column.

  5. On the Monitoring Charts details page, click the File System Monitoring tab to view the monitoring details of the target file system.

     You can also configure alert rules based on metrics to monitor the usage of capacity quotas or the number of files. When a metric for a capacity quota or the number of files reaches the specified alert threshold, Cloud Monitor automatically sends an alert notification. This lets you promptly identify and handle abnormal monitoring data. For more information, see Configure a basic alert rule.

     Metric	Metric name	Description
     BMCPFSFsetCapacityLimit	Allocated capacity of a fileset	The maximum storage space that can be used to write data to the fileset. After the quota is reached, you can no longer write data.
     BMCPFSFsetCapacityUsed	Used capacity of a fileset	The actual used capacity of the fileset.
     BMCPFSFsetInodeLimit	Number of files allocated to a fileset	The maximum number of files and directories that can be written to the fileset. After the quota is reached, you can no longer write data.
     BMCPFSFsetInodeUsed	Number of files used by a fileset	The actual number of files used by the fileset.

• Use the Cloud Monitor API

  • DescribeMetricMetaList: Queries the descriptions of time-series metrics that are supported by Cloud Monitor.

  • DescribeMetricList: Queries the monitoring data of a time-series metric of an Alibaba Cloud service within a specified time period.

  • DescribeMetricLast: Queries the latest monitoring data of a specified monitored object.

  The following table describes the request parameters for CPFS for Lingjun.

  Name	Description
  Namespace	The namespace of the Alibaba Cloud service. The namespace of CPFS is acs_nas.
